SUMMARY Technical Problem

The above-described vehicle seat, however, adopts a structure in which atrim cover (cover body) is configured to be fittable or removable so asto dress the seat with a slide fastener that is stitched to the basetrim cover (particularly in Patent Document 1, the base trim covercorresponds to a main pad cover which wraps around the seat cushion bodyand a side pad upper cover which covers the side part of the pad).Therefore, if the slide fastener is broken, the entire base trim coverneeds to be replaced, thus increasing the repair cost.

Therefore, an object of the present invention is to provide a hookingstructure for a seat that reduces repair cost by enabling a replacementof only a fastening member without a replacement of a base trim cover inthe case of breakage of a fastening member for use in fitting andremoving a dressing cover.

Solution to Problem

In order to achieve the object, the present invention provides a hookingstructure for a seat in which a dressing cover is hooked to be supportedremovably from a seat member provided with a base trim cover, including:a fastening member that is configured from an open-type slide fastenerand is not stitched to the base trim cover, where the open-type slidefastener includes a fastener part that is formed of one fastener halfpart and the other fastener half part and a slider part that slidesalong the fastener part to open and close the one fastener half part andthe other fastener half part; and a plastic fixing member that fixes theone fastener half part to the seat member in a groove part for hookingformed in the seat member, wherein: the fastening member is providedwith a locked part; the fixing member is provided with a flexiblelocking part that locks the locked part; and the other fastener halfpart and the dressing cover are anchored together by an anchoring part.

In this hooking structure, the fastening member is not stitched to thebase trim cover and therefore the base trim cover and the fasteningmember are independent of each other, thus enabling only the fasteningmember to be replaced by releasing the fixing by the fixing member withthe base trim cover left as it is. Therefore, in the case of a brokenfastening member, only the fastening member is able to be replacedwithout a replacement of the base trim cover.

Moreover, the fixing member is made of plastic and has a flexiblelocking part, and therefore the locked part of the fastening member isable to be unlocked by deflecting and deforming the locking part. Thework of deforming the plastic locking part in this manner is able to becarried out with bare hands. Therefore, the hooking structure enables ahooking work or a work of removing the trim cover without using a tool.

Furthermore, the plastic fixing member looks better than a metal fixingmember and is less likely to give an uncomfortable feeling.

The locking part of the fixing member may have a pair of locking clawsthat sandwich the locked part. This type of locking part sandwiches thelocked part between the pair of locking claws to hold the locked partwith being locked by the locking claws.

Preferably the locked part has a wedge-shaped cross section. Pressingthe locked part having the wedge-shaped cross section to the lockingpart of the fixing member causes the pair of locking claws to be pressedapart, which thereby facilitates the work of pushing and locking thelocked part. Furthermore, the locked part is able to be detached fromthe locking part by turning and rotating the locked part sandwichedbetween the locking claws and then pulling the tip of the wedge towardbetween the pair of locking claws.

Preferably, the fixing member has an inclined plane for applying a forceof pushing open the pair of locking claws upon pressing of the lockedpart. Pushing the locked part of the fastening member to the lockingpart causes the pair of locking claws to be pushed open through theinclined plane, thereby enabling the locked part to be easily pushedinto between the pair of locking claws.

The locked part may have a rectangular cross section.

The seat member may be provided inside with an insert member that locksthe fixing member and the fixing member may have a fastening part ableto be hooked on the insert member. The fastening part enables the fixingmember to be locked by hooking the fixing member on the insert member.Moreover, the locked state can be easily released by detaching thefastening part.

The locked part may include a plastic molding product.

The locked part may be formed of a plastic plate integrated into the onefastener half part.

The locked part may be formed of a plastic cord integrated into the onefastener half part.

The locked part may be formed of a plastic cord inserted into the onefastener half part that is sewn into a bag shape.

The locked part may be provided in a joint member that constitutes apart of the one fastener half part.

In the hooking structure, a hole may be formed in the base trim cover sothat the fixing member having passed through the hole locks with theinsert member.

Furthermore, according to the present invention, there is provided ahooking structure for a seat in which a dressing cover is hooked to besupported removably from a seat member, including: a fastening memberthat is configured from an open-type slide fastener, where the open-typeslide fastener includes a fastener part that is formed of one fastenerhalf part and the other fastener half part and a slider part that slidesalong the fastener part to open and close the one fastener half part andthe other fastener half part; and a plastic fixing member that fixes theone fastener half part to the seat member in a groove part for hookingformed in the seat member, wherein: the fastening member is providedwith a locked part; the fixing member is provided with a flexiblelocking part that locks the locked part; and the other fastener halfpart and the dressing cover are anchored together by an anchoring part.

In this hooking structure, in the case of breakage of a fastening memberfor use in fitting and removing the dressing cover, only the fasteningmember can be replaced, thereby enabling a reduction of repair cost.

The locking part of the fixing member may have a pair of locking clawsthat sandwich the locked part. This type of locking part sandwiches thelocked part between the pair of locking claws to hold the locked partwith being locked by the locking claws.

Preferably, the locked part has a wedge-shaped cross section. Pressingthe locked part having the wedge-shaped cross section to the lockingpart of the fixing member causes the pair of locking claws to be pressedapart, which thereby facilitates the work of pushing and locking thelocked part. Furthermore, the locked part can be detached from thelocking part by turning and rotating the locked part sandwiched betweenthe locking claws and pulling the tip of the wedge toward between thepair of locking claws.

Preferably, the fixing member has an inclined plane for applying a forceof pushing open the pair of locking claws upon pressing of the lockedpart. Pushing the locked part of the fastening member to the lockingpart causes the pair of locking claws to be pushed open through theinclined plane, thereby enabling the locked part to be easily pushedinto between the pair of locking claws.

The locked part may have a rectangular cross section.

The seat member may be provided inside with an insert member that locksthe fixing member and the fixing member may have a fastening part ableto be hooked on the insert member. The fastening part enables the fixingmember to be locked by hooking the fixing member on the insert member.Moreover, the locked state can be easily released by detaching thefastening part.

DESCRIPTION OF EMBODIMENTS

Hereinafter, detailed description will be made on preferable embodimentsof a hooking structure for a seat according to the present inventionwith reference to drawings (see FIGS. 1 to 12).

A seat 1 includes a seat bottom 2 movable back and forth on a floorpanel of a vehicle and a backrest 3 capable of reclining to the seatbottom 2. The seat bottom 2 and the backrest 3 are seat members thatconstitute the seat 1 and each include a cushion material 4 made offoam. Moreover, a dressing cover 7 is fittable or removable to or fromthe seat bottom 2 and the backrest 3 by using a hooking structure 10.The seat bottom 2 and the backrest 3 are provided with a plurality oflinear hooking grooves 11 that constitute the hooking structure 10 (seeFIG. 1).

A description will now be made by giving an example of the backrest 3.The cushion material 4 constituting the backrest 3 has a main cushionpart 41 for use in supporting the back of an occupant from the rear anda side cushion part 42 for use in holding the back of the occupant fromthe side (see FIG. 3). The surface of the cushion material 4 is coatedwith the base trim cover 6 by using, for example, an adhesive orintegral foam molding.

The dressing cover 7 is formed of a main surface part 71 placed on themain cushion part 41 of the cushion material 4 and a side surface part72 placed on the side cushion part 42 (see FIG. 3). The main surfacepart 71 and the side surface part 72 of the dressing cover 7 are joinedby a stitched part 74 with their surfaces kept in contact with eachother. When the cushion material 4 and the base trim cover 6 are coveredwith the dressing cover 7 in a state where the front face thereof facingthe seated person side and the rear face thereof facing the cushionmaterial 4 side, the stitched part 74 and a portion ahead of thestitched part 74 of the dressing cover 7 are not exposed to the frontface side (see FIG. 3).

Furthermore, the dressing cover 7, which is hooked to be supported inthe hooking groove 11 by using the fastening member 5, is attached tothe backrest 3 or the seat bottom 2 at its outer periphery by theouter-periphery dressing fastener 8. In the present specification anddrawings, only the arrangement example of the outer-periphery dressingfastener 8 is illustrated (see FIG. 1) and the description of itsstructure is omitted. In addition, although not specificallyillustrated, wadding may be provided between the base trim cover 6 andthe dressing cover 7.

The hooking structure 10 for hooking and supporting the dressing cover 7includes the fastening member 5, the hooking groove 11, an insert wire16, and a plastic fixing clip (fixing member) 30 (see FIG. 2).

The hooking groove 11 is formed of a concave portion 12, which is formedwith a predetermined depth in a vertical direction of the backrest 2along the boundary between the main cushion part 41 and the side cushionpart 42. The hooking groove 11 forms an appearance of the seat 1 andstores a base-side tape part (one fastener half part) 511 of thefastening member 5, which is used for hooking the dressing cover 7.Although the concave portion 12 is compressed and closed between themain cushion part 41 and the side cushion part 42 by elasticity of thecushion material 4 in the normal state, FIG. 3 illustrates the concaveportion 12 that opens so as to make it easier to understand.

Although the backrest 3 is further provided with a hooking groove 11extending in a horizontal direction (in a width direction of thebackrest 3) in addition to the aforementioned hooking groove 11, and theseat bottom 2 is also provided with a hooking groove 11 (see FIG. 1). Inthe present embodiment, however, a description will be continued bygiving an example of the hooking groove 11 that includes the concaveportion 12, which is formed in the vertical direction as described inthe above.

The fastening member 5 is a member that enables the dressing cover 7 tobe fitted or removed in the hooking groove 11 formed in the cushionmaterial 4. The fastening member 5 of the present embodiment is formedof a slide fastener 50 including a fastener part 51 and a slider part 52(see FIGS. 2 and 3). Although any break line is not expressly providedin FIG. 2, the cushion material 4, the fastening member 5, and thedressing cover 7 are only partially illustrated. A cover-side tape part512 (the other fastener half part) of the fastener part 51 of thefastening member 5 is inserted into the hooking groove 11 in the depthdirection D of the concave portion 12 and is engaged with the base-sidetape part 511 for fastening of the fastening member 5, thereby enablingthe dressing cover 7 to be secured to the seat 1 by hooking.

The fastener part 51 of the slide fastener 50 includes the base-sidetape part 511 and the cover-side tape part 512. The base-side tape part511 and the cover-side tape part 512 include elements (teeth) 511B and512B engaging with each other and insert pins (only an insert pin 512Cof the cover-side tape part 512 is illustrated in FIG. 2 and the like)(See FIG. 2 and the like).

The slider part 52 of the slide fastener 50 slides on the fastener part51 in the direction in which the elements 511B and 512B are aligned(hereinafter, the direction will be referred to as “slide direction” andindicated by character S), so that the element 511B of the base-sidetape part 511 engages with the element 512B of the cover-side tape part512 to fasten the fastening member 5 or so that the engagement isreleased so as to release the fastening of the fastening member 5.

The cover-side tape part 512 is stitched together with the main surfacepart 71 and the side surface part 72 of the dressing cover 7 in thestitched part 74 and anchored to the dressing cover 7 (see FIGS. 2 and 3and the like). Although the case of stitching is illustrated here, thecover-side tape part 512, the main surface part 71, and the side surfacepart 72 may be anchored to each other by welding or the like, instead.

A locked part 53 is formed at the edge of the base-side tape part 511.The locked part 53 has an enough width that the locked part 53 is lockedwith the locking part 31 of the plastic clip 30 (see FIG. 2 and thelike).

Although a specific configuration of the locked part 53 is notparticularly limited, the locked part 53 may include a plastic moldingproduct. For example, the locked part 53 may be configured by sewing aplate-like plastic plate 53A on the edge of the base-side tape part 511so as to be integrated into the base-side tape part 511 (see FIG. 2).The plastic member integrated into the base-side tape part 511 in thismanner reinforces at least the portion fixed to the cushion material 4by the plastic clip 30 in the base-side tape part 511, prevents thebase-side tape part 511 from being broken, and makes it easier to keepthe tension acting at the time of hooking constant.

In another example, the locked part 53 may be formed of a plastic cord53B that has been molded along the edge of the base-side tape part 511(see FIGS. 6 and 7). The plastic cord 53B has a wedge-shaped crosssection such as, for example, a triangular-shaped cross section.Moreover, the use of plastic integral molding makes it easier to reducecost required for forming the locked part 53.

In still another example, the end of the base-side tape part 511 is sewninto a bag shape to form a loop 511L and then the plastic cord 53B isinserted into the loop 511L, thereby enabling the configuration of thelocked part 53 (see FIG. 10). Furthermore, if a hole part 511H ispreviously formed in a predetermined position of the loop 511L, thelocking part 31 of the plastic clip 30 is able to be directly lockedwith the plastic cord 53B (see FIG. 10).

The insert wire 16 is buried inside the cushion material 4 of thebackrest 2 and in a portion at a predetermined depth from the bottom ofthe concave portion 12 (see FIGS. 2 and 3: the groove depth direction ofthe concave portion 12 is indicated by character D in FIG. 3). Thepredetermined depth in the above is a depth appropriate for fixing thebase-side tape part 511 of the fastening member 5 to the insert wire 16with the plastic clip 30 in consideration of the size of the plasticclip 30 and the like at the time of fixing (see FIG. 3).

Although a specific shape of the insert wire 16 is not illustrated inthe diagram, the insert wire 16 may be a wire that extends straight in adirection in which the concave portion 12 is formed (in the presentembodiment, the vertical direction along the boundary between the maincushion part 41 and the side cushion part 42) or may be a wire in whicha portion to which the plastic clip 30 is fixed is cranked so as to becloser to the concave portion 12. In addition, both ends of the insertwire 16 are bent and rounded.

The plastic clip 30 is a fixing member that is used to fix the base-sidetape part 511 of the fastening member 5 to the seat member in thehooking groove 11 and has a locking part 31 and a fastening part 32 (seeFIG. 3).

The locking part 31 is a portion that is used to lock the locked part 53of the fastening member 5 and is flexible. The locking part 31 of theplastic clip 30 according to the present embodiment has a pair oflocking claws (locking pieces) 31A facing each other and sandwiches thelocked part 53 with the pair of locking claws 31A to hold the lockedpart 53 (see FIGS. 2 and 3 and the like).

Furthermore, on the back side (a portion facing outward) of each lockingclaw 31A of the locking part 31, there is formed an inclined plane 31Bto which a force of pushing open the pair of locking claws 31A isapplied when the locked part 53 is pressed (see FIG. 3 and the like). Ifthe locked part 53 is thrusted against the locking part 31, the force isapplied to the inclined plane 31B and thereby the pair of locking claws31A are automatically pushed open. Therefore, the locked part 53 iseasily guided so as to be pushed into between the pair of locking claws31A.

The fastening part 32 of the plastic clip 30 is a portion that hooks andlocks the insert wire 16. The fastening part 32 of the plastic clip 30according to the present embodiment is hook-shaped so as to be able tohook the insert wire 16 (see FIGS. 2 and 3, and the like). The plasticclip 30 having the fastening part 32 as described above is able to holdthe fastening member 5 by hooking the insert wire 16 and is able torelease the holding state by removing the hooking.

Moreover, a hole 65 is formed in the base trim cover 6, so that theplastic clip 30 locks the insert wire 16 through the hole 65 (see FIG.2). In this case, the plastic clip 30 directly locks the insert wire 16without intervention of the base trim cover 6, thereby enabling thelocking force to be further increased in comparison with the case wherethe base trim cover 6 intervenes. Moreover, the hole 65 also has afunction of marking 20 that indicates a place where the plastic clip 30should be located. Furthermore, the hole 65 as described above islocated inside the hooking groove 11 and therefore the hole 65 is keptout of sight of a seated person and the like.

Other hooking grooves 11 of the backrest 3 and other hooking grooves 11in the seat bottom 2, and a hooking structure 10 formed by each of thehooking grooves are configured in the same manner as the above-describedhooking structure 10. Therefore, their description will be omitted here.

In the hooking structure 10 for the seat 1 according to the presentembodiment described hereinabove, the fastening member 5 is not stitchedto the base trim cover 6 (in other words, the plastic clip 30, whichfixes [the base-side tape part 511 of] the fastening member 5 to thecushion material 4, merely penetrates the base trim cover 6), andtherefore the base trim cover 6 and the fastening member 5 areindependent of each other and can be separated from each other.Therefore, if the fastening member 5 is broken, it is possible to detachthe plastic clip 30 to release the fixing and to detach only thefastening member 5 for replacement with the base trim cover 6 left as itis. In other words, since only the fastening member 5 is able to bereplaced without replacement of the base trim cover 6, the repair costrequired in the case of breakage of the fastening member 5 can bereduced.

Furthermore, in this hooking structure 10, a metal fixing member, whichrequires a dedicated attachment tool, is not used, but instead, theplastic clip 30, which enables a hooking work with bare hands, is usedas the fixing member, and therefore no tool need not be used. Thisprevents a case of failure in handling or a problem caused thereby thatcould have occurred in the case where an inexperienced worker uses atool. Moreover, the hooking work with the plastic clip 30 is composed ofrelatively simple works such as causing the locking part 31 to lock withthe locked part 53 of the fastening member 5 and hooking the fasteningpart 32 on the insert wire 16, thereby not requiring high proficiency.

The following briefly describes a procedure for hooking the dressingcover 7 in the aforementioned hooking structure 10.

The plastic clip 30 is attached at a predetermined place of the lockedpart 53 of the fastening member 5 (see FIG. 2 and the like). To attachthe plastic clip 30, the plastic clip 30 may be fitted into the end ofthe plastic plate 53A or the plastic cord 53B so as to slide, oralternatively, the plastic clip 30 may be locked by pressing the lockingclaws 31A apart by placing and pushing the plastic plate 53A or theplastic cord 53B against the aforementioned inclined plane 31B.Particularly, the locked part 53 is wedge-shaped like the plastic cord53B, the locking claws 31A can be easily pressed apart.

Subsequently, the fastening part 32 of the plastic clip 30 is allowed topass through the hole 65 of the base trim cover 6 and then is hooked onthe insert wire 16 (see FIG. 2), thereby enabling fastening between thefastening member 5 and the insert wire 16 with the plastic clip 30.

Similarly, in other predetermined places, the fastening member 5 isfastened to the insert wire 16 with the plastic clip 30. As describedabove, the fastening member 5 is able to be hooked into the hookinggroove 11 together with a part of the dressing cover 7 (see FIG. 3).

Additionally, hooking the dressing cover 7 into the hooking groove 11requires both of the work of locking the locked part 53 of the fasteningmember 5 with the locking part 31 of the plastic clip 30 and the work ofhooking the fastening part of the plastic clip 30 on the insert wire 16as described above. Note that, however, the order of the works is notparticularly limited, but either of the works may precede the other.

Moreover, to detach the fastening member 5 from the cushion material 4,the following work is required.

Specifically, fingers are inserted into the hooking groove 11 to pickthe plastic plate 53A up with the fingers in the vicinity of the plasticclip 30 and then to give a twist to and rotate the plastic plate 53A(see FIG. 4). This releases the state in which the locked part 53 (theplastic plate 53A) is locked with the locking part 31 of the plasticclip 30. Thus, the locked part 53 is pulled out from the locking part 31of the plastic clip 30 directly (see FIG. 5). This work is performed forother plastic clips 30 and then the locked part 53 (plastic plate 53A)is pulled out from all the plastic clips 30, thereby enabling thefastening member 5 to be detached from the cushion material 4.

Furthermore, in the case where the locked part 53 is composed of aplastic cord 53B having a wedge-shaped cross section (see FIGS. 6 and7), the plastic cord 53B is rotated in the same manner as the above sothat the wedge-shaped tip faces between the pair of locking claws 31A ofthe plastic clip 30 (see FIG. 8), and the locked part 53 (plastic cord53B) is pulled out from the locking part 31 of the plastic clip 30directly (see FIG. 9). This work is performed for other plastic clips 30and then the locked part 53 (plastic cord 53B) is pulled out from allthe plastic clips 30, thereby enabling the fastening member 5 to bedetached from the cushion material 4.

Furthermore, in the case where the plastic cord 53B is inserted into theloop 511L of the base-side tape part 511 (see FIG. 10), the plastic cord53B is similarly rotated so that the wedge-shaped tip faces between thepair of locking claws 31A of the plastic clip 30 (see FIG. 11), and thelocked part 53 (plastic cord 53B) is pulled out from the locking part 31of the plastic clip 30 directly together with the loop 511L (see FIG.12). This work is performed for other plastic clips 30 and then thelocked part 53 (plastic cord 53B) is pulled out from all the plasticclips 30 together with the loop 511L, thereby enabling the fasteningmember 5 to be detached from the cushion material 4.

As described above, the fixing member in the hooking structure 10according to the present embodiment is the plastic clip 30 and has theflexible locking part 31. Therefore, the locked part 53 of the fasteningmember 5 is able to be unlocked by deflecting and deforming the lockingpart 31. The work of deforming the plastic locking part 31 in thismanner is able to be performed with bare hands, which enables a hookingwork or a work of detaching the fastening member 5 without using a tool.

Although the above embodiments are merely preferred embodiments of thepresent invention, the present invention is not limited thereto, butvarious modifications can be made without departing from the scope andprinciples of the present invention. For example, the seat 1 to whichthe hooking structure 10 according to the present invention is appliedcan be used for an automotive seat, an aircraft seat, a passenger shipseat, a railway vehicle seat, and the like.

Furthermore, the provision of the insert member such as the insert wire16 in the cushion material 4 as described above preferably alleviateslocal deformation of the cushion material 4 in the hooking structure 10and makes it difficult for the plastic clip 30 to move or come off. If,however, the plastic clip 30 can be firmly fixed only with the use ofthe cushion material 4, the insert member need not necessarily beprovided.

Furthermore, while the above embodiments illustrate the cases where thesurface of the cushion material 4 is coated with the base trim cover 6by using, for example, an adhesive or integral foam molding (see FIG.3), they are merely preferred embodiments. Besides, for example, thebase trim cover 6 may be fixed to the fastening member 5 with theplastic clip 30 and also may be secured to the cushion material 4 (seeFIG. 13).

Furthermore, the present invention is also applicable to the hookingstructure 10 for the seat 1 not provided with the base trim cover 6 (seeFIGS. 14 and 15). In this seat 1, even if the slide fastener 50 isbroken, no base trim cover is present in the first place and thereforethe work of replacing a base trim cover itself is unnecessary.Therefore, similarly to the above embodiments, the locked part 53 of thefastening member 5 is able to be unlocked without using a tool bydeflecting and deforming the flexible locking part 31 of the plasticclip 30. Moreover, in this seat 1, the simplification of the base trimcover enables a reduction in the number of parts and weight savingcorrespondingly.

Although the hooking structure 10 in which the locked part 53 is formedat the edge of the base-side tape part 511 has been illustrated in theabove embodiments, it is a merely preferred example in the case ofproviding the locked part 53 in the fastening member 5. Specifically,the locked part 53 may be directly formed in a part of the base-sidetape part 511 (see FIG. 6) or another member with the locked part 53formed in a part thereof may be attached so that a part of the base-sidetape part 511 is a locked part 53. For example, in the embodimentillustrated in FIG. 16, a retrofittable suspender (joint member) 511S isused for the base-side tape part 511, where the locked part 53 ispreviously provided at the edge of the suspender 511S. Then, the otheredge of the suspender 511S is attached to the base-side tape part 511,by which the base-side tape part 511 is provided with the locked part53. As a method of attaching the suspender 511S to the base-side tapepart 511, sewing, adhesion, pinning, or the like is used. According tothis, the locked part 53 made of the plastic plate 53A and the like ispreviously plastic-molded in the suspender 511 and then theplastic-molded locked part 53 can be provided in the fastening member 5together with the suspender 511S by sewing or the like.

Furthermore, in the structure in which the locked part 53 is previouslyplastic-molded in the suspender 511S in this manner, a long locked part53 is previously plastic-molded in a long suspender 511S whose detailedsize is not determined, so that the suspender 511S can be cut into apredetermined length and used. According thereto, the present inventionis able to easily cope with various lengths of products and thusincreases the versatility. In addition, it eliminates the necessity ofseparately making molds in plastic molding, thereby also having a costadvantage.
